$Ï$ Ori and $Ï$ Lib: Two new massive heartbeat binaries
arXiv:1801.05985
Abstract
We report the discovery of two massive eccentric systems with BRITE data, $Ï$ Ori and $Ï$ Lib, showing heartbeat effects close to the periastron passage. $Ï$ Lib exhibits shallow eclipses that will soon vanish due to the apsidal motion in the system. In neither system, tidally excited oscillations were detected.
